An early-access hands-on of Fable 5.2 (claude-fable-5-2), skipping benchmarks:
What's different
- 30% faster output than 5.1, plus up to 2.5x fast mode in Claude Code/API (watch costs)
- Medium effort suffices; fewer tokens than 5.1 on hard tasks
- 55% fewer blocks than 5.1
- API price dropped from $10/$50 to $8/$40 per million tokens
- Paid plans get 1–3 free usage resets this week
- Vision is a headline upgrade: diagnosed a broken page from a screenshot alone
What's the same: same base as the security/bio-gated Mythos; still no knowledge of webpage changes without search; still burns limits faster than Opus/Sonnet.
Try first: have it review your last model's project for bugs; feed it broken UI screenshots or whiteboard photos; ask for its plan before acting; rerun a task 5.1 kept failing with the same prompt. Avoid day one: giant refactors, high effort everywhere, using it as a search engine.
